F2P Pokemon Style Monster MMORPG

[Gors]

I am going to jump in and say I don't see the reason of this game being blocked by game companies at all.

I don't know a lot about copyright laws, but I believe that it is legal-action worthy if he's using copyrighted material for profit. You can even read on the op:
"MonsterMMORPG was once called as PokemonCraft. It was a Pokemon MMORPG being developed by me. It started as my graduation project . I am a computer engineer. I started developing at 2009 and since then i am developing. Game was up almost with 99.99% until Nintendo forced to shut down our game. But i did not give up on my game and removed all of the nintendo copyrighted stuff from my game. Now it is a unique Monster MMORPG game."

This means, he is no longer using copyrighted material that could put him in problems.

"but he's using the same engine of that Pokémon game"

That doesn't matter, as he coded the engine himself in C#, if I'm not mistaken. That means, the coding is also 100% his. Even if he copied Pokémon gameplay, I don't know if it is lawsuit-worthy because if so, Digimon and other monster-collecting games would also have had problems too.

tl;dr it's not a Pokémon game and thus it's not lawsuit worthy, in my point of view. If anyone wants to add something to this discussion/correct me, go ahead.
